A light wave with a wavelength roughly between 350 and 800 nanometers will be seen, i.e. perceived by your visual aparatus ... if it enters your eye. (This is probably the main reason that such waves are often called "visible light".) If somebody on one side of the room shines a laser pointer at another guy on the other side of the room, and you're standing in the front of the room by the blackboard watching them, then no, you won't see the laser light crossing the room, because none of the energy enters your eye. But if there's a bit of dust in the air, and a bit of the laser light gets scattered in your direction and enters your eye, then you will see it.
What else can I help you with?
Light waves are classified as what waves?
Optical light waves are "Electromagnetic" waves. The colour seen is dependent on the wavelength of the light. Electromagnetic waves are transverse waves where the oscillation is 90 degrees to the direction of travel (unlike sound waves which are longitudinal).
What travels in waves?
Mechanical waves such as sound and water waves.Electromagnetic waves, such as light, radio, microwaves, x-rays.
How is light different than mechanical waves in terms of their propagation and behavior?
Light waves and mechanical waves differ in their propagation and behavior. Light waves are electromagnetic waves that can travel through a vacuum, while mechanical waves require a medium, such as air or water, to propagate. Light waves also travel at the speed of light, while mechanical waves travel at varying speeds depending on the medium. Additionally, light waves exhibit properties such as interference and diffraction, which are not typically seen in mechanical waves.
Which electromagnetic waves enables colours of an object to be seen and recognized?
Visible light.
Difference between infrared waves and red light waves?
Infrared waves have longer wavelengths compared to red light waves. The wavelengths of infrared waves are too long for the naked eye to see, while red light waves can be seen as part of visible light.
What is a light wave?
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.
Will an explosion be seen or heard first?
In most cases, the sound of an explosion will be heard before it is seen. This is because sound waves travel slower than light waves, so the sound reaches a person's ear before the light reaches their eyes.
Can sound waves be seen?
No, you cannot see sound waves. Sound waves move more quickly than we can process with our eyes. Technically, sound waves are invisible.
What light waves can be seen by the human eye?
Any light wave with a wavelength between roughly 350 to 750 nanometers.
Is all electromagnetic waves invisible?
No, not all electromagnetic waves are invisible. While some, such as radio waves, microwaves, and infrared waves, are invisible to the human eye, others, like visible light, ultraviolet light, and X-rays, can be seen or detected with the right equipment. For example, visible light waves are responsible for the sense of sight.
Which property of light wave makes the image seen through lenses?
The property of light waves that allows an image to be seen through lenses is the refraction of light. When light waves pass through a lens, they are bent or refracted, causing the rays to converge or diverge depending on the shape of the lens, resulting in the formation of an image.
What happens if 2 light waves with the same amplitude interfere?
Their amplitude is not the important variable - their frequency is . If two light waves of the same frequency interact, then an interference pattern will be seen. This is the basis of the 'double slit' experiment designed to demonstrate that light may be considered to indeed be waves.
